McConaughey, 38, announced the pregnancy in January with an effusive message on his website. "Got some blessed news, a celebration of life and bounty, a newborn conceived, yes, my girlfriend Camila and I made a baby together.

"We are stoked and wowed by this miracle of creation and this gift from God, and so excited for the adventure that will come in raising this child, being a mother and father, and shepherding him or her through life," he said.

"Wish us the best, keep us in your prayers and God bless evolution. Thanks for being fans of me and my work and now this new and miraculous chapter in my life."
